The listing
Novakid is an online English school for kids. The Visitor Squad owns the funnel from first visit to paid lesson: landing pages, registration and booking, blog, and the visitor's personal account. We track two key metrics, visitor → lead and visitor → booking, and test almost everything we ship through experiments.
This is a backend-first role: about 70% backend (Python, some Node.js) and 30% frontend (React/TypeScript). You'll own the server side of the funnel: APIs behind registration, booking and the visitor account, attribution, and server-side integrations with ad platforms. When a feature needs frontend work, you'll take it end-to-end yourself. You'll work within the squad's processes: planning, grooming, code review, sprints and releases.
Key Responsibilities
Design, build and maintain Python services and APIs behind the funnel: registration, booking and the visitor account
Build and own server-side integrations with ad platforms (Meta CAPI, TikTok Events API and similar): event delivery, deduplication, retries and monitoring
Own attribution on the backend: end-to-end visit tracking, UTM persistence, and diagnosing gaps in V2L/V2B data
Keep services fast and reliable: caching, query optimization, debugging server-side rendering in our Node.js/Express layer
Investigate production incidents through Sentry and see them through to resolution
Support A/B testing on the server side: feature flags, rollouts, and cleanup after experiments
Ship frontend changes in React/TypeScript when a feature needs it
Requirements
5+ years of production backend development in Python, including services you designed, shipped and supported in production yourself
Strong backend fundamentals: API design, relational databases and SQL, caching, background jobs, and integrating third-party APIs (auth, rate limits, retries, idempotency)
Production debugging experience: logs, error tracking, finding the root cause of an issue
Node.js: comfortable reading and changing an Express service
Working frontend skills: enough TypeScript and React to deliver a feature end-to-end. Expert level not required.
An understanding of how tracking data travels from click to report, and the ability to find where it gets lost
Product mindset: you work with metrics and hypotheses, not just tickets
Fluent English
Nice to Have
Server-side conversion tracking (CAPI, Events API, server-side GTM)
BigQuery: checking your own hypotheses with data
CDN and edge caching (CloudFront or similar)
GDPR and consent mechanisms
E2E testing with Playwright or Cypress
